Adding an API to reserve fixed numbers would work but:
* if the fixed numbers are chosen by the driver ("drm_reserve_id(u64_max
-1)"), I don't see the benefit over the current patch
* if the fixed numbers are allocated by drm (drm_reserve_id("vm_update") ->
u64), it would then require a way

That won't give us fixed numbers for in kernel clients.
That's fine, then let

That's fine, then let's come up with an API that reserves fixe

Yes, IDR is basically xarray under the hood. But, a raw xarray

Not the theoretical overlap is not of any concern for me. What I dislike is

I think it would be nicer if we could use negative values for the kernel

would need to adjust the
